Set to be unveiled at the Paris Motor Show, at which point pricing will also be announced, the brand’s best-selling model will launch with a range of four petrol and two diesel engines.

Petrols include two versions of the new 1.0-litre, three-cylinder ECOTEC Direct Injection Turbo, producing 89bhp or 113bhp and with peak torque available from a diesel-like 1,800rpm, promising strong in-gear performance.

The lower-powered version of this engine returns 54.7mpg on the combined cycle, Vauxhall has confirmed, and will be joined by 1.2 and 1.4-litre non-turbo petrol engines producing 70bhp and 89bhp respectively.

Diesel engines comprise two revised versions of the 1.3 CDTi, with 74bhp and 93bhp, featuring a new turbocharger for smoother acceleration and low noise and Start/Stop technology as standard. Fitted with brake energy recuperation, the more powerful diesel engine is also the range’s economy leader, returning 87.8mpg with CO2 emissions of 85g/km.

Vauxhall has also confirmed some of the specifications ahead of its Paris debut, with a heated windscreen, hill start assist and tyre pressure monitoring standard across the range, and the IntelliLink infotainment fitted to all except the entry-level model.
